WENTZ, OF PASSAIG, NEW JERSEY SHEARS Application filed May 15,

My invention relates to improvements in shears, scissors and the like.

In the manual cutting of material by means of shears and the like, it is desirable to prevent the cutting blades from complete closing as, when the blades close for their entire length, the material being cut will then be released from the grip of the blades or cutting members, the line being out must then be relocated and rough and uneven cutting and loss of time results therefrom.

When, however, the cutting blades are prevented from complete closing for their entire length, the grip of the blades on the material being cut is retained and a much better result is attained with the saving of time.

An object of my invention is to provide a novel and useful means for preventing the complete closing of the blades in operation, while permitting the free and full use of the implement within predetermined limits; another object of my invention is to provide means for locking the blades in closed relation; another object of my invention is to provide means whereby bothof the above objects may be attained in the same implement and a further object of my invention is to provide means whereby an implement equipped with my improved device may be used in the normal manner and the device placed in neutral position, as may be desired.

A preferred embodiment of my invention is illustrated in the accompanying drawings, in which Figure 1 is a view of a pair of shears equipped with my improved device and stopped short of complete closing of the blades,

Figure 2 is a view of the shears latched in closed relation,

Figure 3 is a detail showing the spring latch and stop means in neutral position to permit the free and normal operation of the shears, and

Figure 4 is a view of the latch and stop means.

Similar characters of reference refer to similar parts throughout the several views.

The blades 1 and 2 are provided with inte- 1929. Serial No. 363,141.

the handle 3 by means ofa bolt'9 or the'like, 3 .and comprises a base section 8 adapted to lieon the handle 3 and an upturned spring section 10 having its free end 11 bent over to form a hook. 1 V r I preferably form in the base 8 of the spacing member 8, two raised or loop sections 12, 13 lying on both sides of the perforated aperture 14, provided therein for the reception of the bolt 9 on which it rotates.

I also provide therein a cut out seat 16 adapted to interchangeably engage the positioning knobs 6 and 7 Y On the inner face of the handle 1, I provide a nose 17 adapted to be engaged by the bent I over hook 11 of the spring 8.

My device being thus assembled, the spacing member 8 will normally prevent the out ting blades from completely closing for their entire length, as the upturned section 10 will contact with the handle 4, as the handles 3 and e are brought together in the operation of theimplement, the handles and blades be ing free to operate within the limit fixed by the spacing member 8. 7

When it is desired to lock or latch the blades in closed relation, the upturned section 10 of the spacing member 8 may be manually drawn back permitting theblades to be closed-and, when released, the hook section 11 thereof will spring forward and engage the nose 17, thus latching the handles and their blades in closed relation To release the handles and permit the free operation of the implement, it is only neces-v sary to again draw back the free end or hook section 10 of the spring 8 until the nose 17 is free, when the implement may be operated as before.

When it is desired to use the implement without the interference of the spring;mem-,

her, the free end 15 or" the spring member 8 is raised over the knob 7 and the same is rotated on its pivot 9 until the knob 6 is engaged by the seat 16 and the spacing member thus placed in neutral position, when the implement may be freely operated.

I do not intend to limit my invention to the particular details of construction shown nor to a structure in which the catch or stop member is rotatable, as it is obvious that the details may be modified or the catch and stop member may be otherwise secured to the shears without departing from the spirit of my invention.

Having thus described my invention, What I claim is:

1. In a device of the character described, the combination of a pair of cutting blades and integral handles pivotally connected, stop means on one of said members compris in a leaf spring set on one of the handles, a section upturned and extending therefrom in the direction of the other handle, said upturned section having a hook adapted to be detachably engaged by the other said handle to lock the handles inclosed relation.

2. In a device of the character described, the combination of a pair of cutting blades and integral handles pivotally connected, and stop means associated therewith comprising a section adapted to lie on one of said handles, pivot means rotatably securing said section thereon whereby it may be ro tated to neutral position, knobs on said handle adapted to adjustably position said stop means and a hook thereon adapted to engage the other said handle to prevent the complete closing of the blades.

3. In a device of the character described, the combination of a pair of pivotally connected cutting and handle members and a latch meansthereon, said latch means comprising a. substantially L-shaped member-rotatably mounted on one of said handles and adapted to normally contact with the other of said handles to prevent the complete closing of the cuttingmembers, spring means thereon adapted to detachably secure the cutting members in closed relation, and means for adjustably positioning the said latch means in operative and inoperative position.

4. The combination of a pair of pivotally connected integral blade and handle members, stop means on one of said members and adapted to space the said blades short of complete closing position and comprising a base section, pivotally secured to one of said handle members and having an upturned free end, a hook section on said free end and adapted to detachably engage the other of said handle members and knobs on said first named handle member adapted to adjustably position said stop means.

5. In a device of the character described, the'combination of a pair of pivotally connected blade and handle members, a latch means adjustably secured on one of said handles, knobs on said handle adapted to position said latch means, a base section on said latch means having an upturned free endand a hookthereon, said hook being adaptedvto detachably engage the other of said handle members.

6. In a device of the character described, the combination of a pair of members each comprising a cutting blade and a handle, said members being pivotally connected, a nose on one of the said members, means on the other of the said members adapted to engage the said nose, the said means comprising a leaf spring secured to the said last mentioned member and having an upturned section normally positioned in the path of the said nose Whenthe handles are moved toward each other and thereby preventing the closing of the handles and blades and being adapted to be drawn out of the path of the said nose to permit the closing of the handle-s.

In testimony whereof I affix my signature.
